Answer:

  • 50x⁴ - 20x² + 1 = 0

1. <u>Quadratic form</u>

  • 50(x²)² - 20x² + 1 = 0

2. <u>U is</u>

  • x² = u

3. <u>U- substitution</u>

  • 50u² - 20u + 1 = 0

4. <u>Find the discriminant and identify roots</u>

  • d = (-20)² - 4*1*50 = 200
  • u = (20 ± √200)/100
  • u = (2 ± √2)/10

<u>Solve for x</u>

  • x² = (2 ± √2)/10
  • x = ± √((2 ± √2)/10), four roots

If you divide the total distance traveled on a car trip (as determined by the odometer) by the elapsed time of the trip, are you
PSYCHO15rus [73]

In general, you're calculating the magnitude of average velocity. In fact, speed is a vector, and as such it also has a direction and orientation.

So, if you compute the average speed, you're assuming that you went directly from point A to point B, which is basically never the case.

If, instead, you actually moved on a straight line from point A to point B, then the two quantities are the same.
